SPECIFICATION forming part of Letters Patent Ilo. 716,018, dated December 16, 1902.

Application filed October Il, 1902. Serial No. 126,874. (No model.)

To @ZZ whom it may con-cern:

Beit known that LGDILON Fenna, a citizen of theFrench Republic, residing at Montreal, district of Montreal, Province of Quebec,

5 Canada, have invented certain new and useful Improvements in Nut-Locks; and I dol hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the front side the plate 1/1 carries a pair of overhanging lug-pieces 1S, riveted thereto by rivets 19 and having projecting concave anges 20, adapted to lit close around the bolt, while permitting it to pass through the same freely. These anges 2O are sufficiently offset from the plate 111 to permit the passage between them and the plate 14 of-the key 13, which has a pair of legs 21, adapted to straddle the threaded portion of the bolt 10, and these are same. preferably brought down to an edge 22 on My invention relates to an improved nuttheir inner face, so as to catch inthe threads lock for locking the track-bolts of a railwayof the bolt.

track', and it consists in Ithe construction and combination of parts hereinafter described, and more particularly pointed out in the claims.

In the drawings accompanying this specification, Figure 1 is a side elevation of a railjoint provided withiny improved nut-lock. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 1. Fig'. 3 is aplan section through the center of a bolt, taken on the line ply inserted over in Figs. 2 and 3, and the key 13 is then inserted between the anges 2O and the plate 111 and hammered down bythe application of a hammer on its head 23, which will effectively lock the nut against turning and prevent the nut-lock from being accidently removed.

Changes within the scope of the following 3 3 of Fig. 1. Figs. 4 and 5 are detail perclaims may be madein the form and construcspective views from the rear and front side, tion of the parts without departing from the respectively, of the socket-piece forming a spirit of my invention, and I desire it to be part of my improved nut-lock; and Fig. 6 is a similar view of the key.

The same numerals of reference denote like parts in all the figures of the drawings.

In the drawings, 7 and 8 designate the abutting ends of two rails, 9 a pair of joint-plates, 10 a track-bolt, and 11 the uut thereof, all of these being of the usual or any preferred pattern.

The parts of my nut-lock are two in number, (designated, respectively, 12 and 13,) the first of which is shown in perspective rear and front views in Figs. Lt and 5 and the second in Fig. 6. These two parts constitute the socket and key of the nut, as will beobserved. The part 12 is in the form of a square plate 14, having a central hexagonal aperture 15, adapted to iit the sides of the nut 11, and preferably, also, a hexagonal sleeve 16, adapted to fit over the nut and of the same width thereof, so that its end strikes against the side of the joint-plate 9. The lower edge 17 of the plate 13 strikes against the lower iiange to make such modifications in the form and dimensions as will be apparent to those skilled in the art.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A nut-lock comprising a socket-piece having a polygonal socket adapted to fit the hut and a projecting plate 14 adapted to strike against the base of the rail or joint-plate te preventsaid socket from turning, a recess in said socket adapted to receive a key, and a key adapted to straddle said bolt and to be driven into said recess to lock the socket-piece in place, substantially as described.

2. A nut-lock comprising a socket-piece having a polygonal recess adapted to receive a nut and prevent it from turning therein, means for preventing said socket-piece from turning relative to the rail, a pair of lug-pieces secured on one face of said socket-piece and having danges slightly offset from said socketpiece, whereby to receive a key, and a key On its adapted to be driven between said flanges to prevent this plate from turning.

understood, therefore, that I reserve the right and socket-piece und to struddle the boltand key adapted to strnddle the bolt and having to interlock with the threads thereof, subtheinterioredgesofitslegssliarpened,\vhe1e stantially as described. by to strike between the threads of said bolt 3.
